#¨¨#¨¨#¨¨# TRAINS  ARE  SO  CONSTRUCTED  THAT  THEY ##¨#¨##¨#¨
#¨##¨##¨## HAVE TO FOLLOW  A SET PATH. THIS PATH IS ¨#¨#¨¨#¨#¨
#¨¨#¨¨#¨¨# CALLED A "RAILWAY", WHICH  IS  COMPRISED ##¨#¨##¨#¨
#¨##¨##¨## OF  TWO METAL RAILS, HENCE ITS NICKNAME. ¨#¨#¨¨#¨#¨
#¨¨#¨¨#¨¨#                                          ##¨#¨##¨#¨
#¨##¨##¨## BECAUSE  THE  LOW FRICTION  BETWEEN  THE ¨#¨#¨¨#¨#¨
#¨¨#¨¨#¨¨# WHEELS OF THE TRAIN  AND THE RAIL METAL, ##¨#¨##¨#¨
#¨##¨##¨## THERE ARE LIMITS FOR  HOW ACUTE  A CURVE ¨#¨#¨¨#¨#¨
#¨¨#¨¨#¨¨# CAN BE,  AND EVEN MORE SO  FOR  HOW MUCH ##¨#¨##¨#¨
#¨##¨##¨## THE  GROUND  UNDER  THE  RAILS  CAN   BE ¨#¨#¨¨#¨#¨
#¨¨#¨¨#¨¨# SLOPED. THUS A  RAILWAY IS OFTEN NOT LED ##¨#¨##¨#¨
#¨##¨##¨## ON TOP  OF HILLS, RATHER THROUGH THEM IN ¨#¨#¨¨#¨#¨
#¨¨#¨¨#¨¨# TUNNELS   (IF  THEY   ARE   LARGE),   OR ##¨#¨##¨#¨

#¨¨#¨¨#¨¨# RAILS,  BUT NOT TOO CLOSE,  OR THEY WILL ##¨#¨##¨#¨
#¨##¨##¨## BE  CUT  DOWN BY THE  RAILWAY  JANITORS. ¨#¨#¨¨#¨#¨
#¨¨#¨¨#¨¨# THERE  WILL  BE PLAINS,  AND  BODIES  OF ##¨#¨##¨#¨

#¨¨#¨¨#¨¨#       THE WAY, THERE IS INFORMATION      ##¨#¨##¨#¨
#¨##¨##¨## SCATTERED,  OFTEN  PUT  ON TOP OF POLES, ¨#¨#¨¨#¨#¨
#¨¨#¨¨#¨¨# TO BE INTERPRETED  BY THE TRAIN DRIVERS. ##¨#¨##¨#¨
#¨##¨##¨## DIFFERENT  PARTS  OF  THE  RAILWAY  HAVE ¨#¨#¨¨#¨#¨

#¨¨#¨¨#¨¨# IS  SIGNALED BY  RED  OR  GREEN  LIGHTS. ##¨#¨##¨#¨
